TRIM MOLDIN G.

original mutation mea nay s, 199s, serial-fno. 637,585. Divided and this application mea February 11,' 192e. serial m. 87,521.

The present invention which. is divided out of a previousva plication for a patent on a trim molding, led by me on May 8th, 1923, Serial No. 63'( ,585, relates to a molding used for concealing the fastening means of trimming, panels and` other parts having vmeeting or fastened edges.

I am aware that' other devices have been arranged and constructedfor.- securing the molding to the supporting body in such,4 a

manner that thesecuring means are con cealed. The present invention, however, has l certain features which impart to it advantages over known structures. I t is desirable that the molding'rest firmly in engag ment with the supportingw surface upon which mounted so as to press tightly against the surface to retain panels or other sepa rate parts in a position of firm mounting. It is also desirable that the'molding itself be free from excessive vibration or rattling and it is an object of the present invention to provide a molding with attaching means whereby these advantages maybe attained andin which the necessary features may be incorporated. Another object of the present invention is theprovision of `a molding having attaching means co-operating with the mo din for preventing any rattlin regardless o the jarring loose or vibration of theattaehing means.

Other objects will appear hereinafter.

The invention consists in the combinationand arrangement of scribed and claimed. v

The invention will be best' understood fromja reference to the accompanyin draw-v ings, which vforma part of thls specification and in which, v Fig. 1 is a perspective view of a section of molding embodying the invention show-A ing the end of the invention in perspective cross section.

Fig. 2 is a perspective view of the molde parts hereinafter dein j Fig. 3 is a perspective view of the attachin member of the'invention.

ig. 4 is a diagrammatic viewV illustrating the operation of the invention.`

In Fig. 1 I have shown mounted upon the supportmg body 8 a pair of adjacent panels 9, and 10.' yThe invention is adapted for use in covering the meeting edges of these panels which are `tacked or otherwise suitably secured to the supporting body 8. To this end I have provided a strlp of metal 11 which has its edges curled to form cylindrical bodies 12 and 13, the molding itself comprises a strip of trough-shaped metal -formed arcuate and has its edges 15 and 16 turned inwardly, as clearly appears in Fig. 1. Thestrip 11is secured to the supporting bodyS by nails 17 or in any other suit-V ab e manner so that this strip 11 will overlie the space betweenthe edges of the panels 9 and 10 and cover their edges. In order to conceal the fastening of the strip 11 the molding 14is clamped over the vcylindrical curled portions '12 and 13. This is done by snapping the molding strip 14 over the cylindrical bodies 12 and 13, the inturned edges 15 and'16 of the molding strip 14 springing apart to permit the snapping of these edges .in locking position on the cylindrical bodies 12and13. j

. Itis evident that when the edges 15 and 16 are passing the center'` of the cylindrical ,bodies 12 and- 13 that the springing apart of the ed es 15 and 16 is at the maximum so thatw en moved@ below the center vof the cylindrical bodies 12 and 13 the inturned edges or flanges 15 `'and 16 tend inresponse to thel resiliency. ofthe metal from which the molding 14 lssconstructed to move downwardly on the cylindrical bodies 12 and 13 and inwardl toward eachother. account the an es or inturned edges 15- and 16 are held by t e resiliency of the moldin 14 in close engagement with the panels 9 an 10, thus serving `to retain the panels in close engagement with the su porting'body 8. In normal position when' t e flanges of the inturned edges 15 and 16 are lying in close engagement with the anels 9 and 10, the inturned edges of the anges 15 and 16 are still sprung slightly apart out of their normal position, so that there is a tendency of On this' the inturned edgesor flanges 15 and -16- tov of these parts even should the strip 11,

vthrough' becomlng loose on its mountings to the body 8 be lifted from or jarred slightly loose of the supporting body 8. In this con-' nection it will be noted vthat| there is an inward pressure of the inturned edges on Aa surface which etends angularly to thebody 8, this surface being the periphery of the. cylindrical portions 12 and 13 so that the inward pressing of the flanges or inwardly directed edges 15 arid 16 is directed against an arcuate body for effecting or at least tending-to eHect an approach of the molding to the su porting body 8.

It is t us seen that the device serves to bind the paneling into close engagement with the supporting body 8 and that the .device automatically locks itself' against the Having thus described my invention'fvhat I claim as new and desire to secure by Letters Patent is:

1. A trim molding. of the class described, comprising: a. fastening strip adapted for mounting on a supporting surface and having its longitudinal edges curled'to form.

arcuate bearing surfaces; a trough shaped molding having'its edges Iturned inwardly toward each other .and providing planar 'bodies lying in the same plane, said molding being adapted for snapping over said arcnate bearing surfaces, the edges of said planar bodies engaging against said supporting surface in response to the resiliency of the material from which saldy molding is made, said planar bodies being normally, while mounted on said -fastening strip, retained beyond normal separation, the resistance of said arcuate bearing 'surface to the relative inward movement ofthe edges of said planar'bodies bein dependent upon the relative location of sai bearing surface and said supporting surface, said arcuate bearing surfaces being normally free from en gagement with'the main bodyy of said molding. l

2. A trim molding of the class described, comprising: a Ifastening strip adapted for mounting oli a supporting surface and having its longithdinal edges curledv to form arcuate bearing surfaces; a trough-shaped molding having its edges turned inwardly toward each. other fand providing planar bodies, said molding being adapted for snapping over said arcuate bearing surfaces, the edges of said lanar bodies engaging said supportin sur ace in lresponse to the resiliency of t e material from which said molding is made, said planar bodies being nor'inally, while mounted on said fastening the resistance o f said arcuate bearing surfaceto the relative inward movement of the strip, retained beyond normal.; separation,l

edges of said planar bodies being dependent upon the relative location of said bearing surface 'and lsaid supporting surface, said arcuate bearing surfaces being-normally free from engagement with the main body of said molding.
